背景:油性皮肤,以过度的皮脂生产为特征,可能会导致痤疮,并由于外观变化而产生社会心理影响。最近的研究表明,人们对控油治疗感兴趣,高岭土和膨润土成为有希望的选择。尽管有潜力,对这些成分的全面研究仍处于起步阶段。
目的:本研究旨在评估粘土面膜(LaRoche-PosayEffaclarSebo控制面膜)在减少皮肤油性和痤疮方面的功效,及其使用的安全性。
方法:在本研究中,纳入75名油性或混合性皮肤的成年人,并在4周内每周两次使用粘土面膜。临床评估,使用像Sebumeter这样的仪器,蒸气计,和角膜计,在基线进行,在1、2和4周后,评估痤疮病变,皮肤刺激,皮脂含量,和皮肤水合作用。参与者的自我评估问卷也用于主观评估。相应地进行统计分析。
结果:研究显示痤疮相关结果有显著改善,皮脂含量,皮肤均匀度,角质层含水量,应用粘土面膜后的经皮水分流失。孔隙面积和卟啉面积均无明显变化。耐受性评估显示干燥和刺激减少,自我评估表明产品可接受性和感知的控油有效性。
结论:这项研究证明了粘土面膜在治疗痤疮和油性皮肤方面的功效,改善水合和质地。观察到皮肤参数和高产品安全性的显着改善,支持其适用性。
BACKGROUND: Oily skin, characterized by excessive sebum production, can lead to acne and have psychosocial impacts due to changes in appearance. Recent research has shown interest in treatments for oil control, with kaolin and bentonite emerging as promising options. Despite their potential, comprehensive studies on these ingredients are still in the nascent stages.
OBJECTIVE: This study aimed to assess the efficacy of a clay mask (La Roche-Posay Effaclar Sebo-Controlling Mask) in reducing skin oiliness and acne, and its safety for use.
METHODS: In this study, 75 adults with oily or combination skin were enrolled and provided with a clay mask for twice-weekly use over 4 weeks. Clinical assessments, using instruments like Sebumeter, Vapometer, and Corneometer, were conducted at baseline, and after 1, 2, and 4 weeks, evaluating acne lesions, skin irritation, sebum content, and skin hydration. Participant self-assessment questionnaires were also utilized for subjective evaluation. Statistical analyses were performed accordingly.
RESULTS: The study revealed significant improvements in acne-related outcomes, sebum content, skin evenness, stratum corneum water content, and transepidermal water loss following the application of the clay mask. Pore area and porphyrin area showed no significant changes. Tolerance assessment showed reduced dryness and irritation, with self-assessment indicating high product acceptability and perceived oil control effectiveness.
CONCLUSIONS: This study demonstrated the clay mask\'s efficacy in managing acne and oily skin, improving hydration and texture. Significant improvements in skin parameters and high product safety were observed, supporting its suitability.
